Abstract (en)
[origin: US2009312460A1] A non-ionic polyether-polyester copolymer for extending workability to a cementitious mixture containing hydraulic cement and water, wherein the copolymer includes residues of at least the following monomers: Component A including an ethylenically unsaturated carboxylic acid ester monomer having a moiety hydrolysable in the cementitious mixture, wherein the hydrolyzed monomer residue has an active binding site for a component of the cementitious mixture; and, at least one of: Component B including an ethylenically unsaturated, carboxylic acid ester or alkenyl ether monomer having at least one C2-4 oxyalkylene side group of about 1 to 30 units; or, Component C including an ethylenically unsaturated, carboxylic acid ester or alkenyl ether monomer having at least one C2-4 oxyalkylene side group of 31 to about 350 units; wherein the molar ratio of Component A to the sum of the molar ratios of Component B and Component C is about 1:1 to about 10:1.
